I bought your product in thinking this is the answer to my brake dust problem. Let me tell you something. Luckily I have calmed down before I sent this message. Your product is by far the worst thing on the market and I guess I should have read the comments before I used it. I am looking at $1200 to replace my rims. 10 thumbs down for this product and plus I will NOT use any of your product again...... User's recommendation: Stay away unless you want to buy new rims!
